Gas Detector for paint room

Why must Gas Detectors be installed in the paint room?

We all know that there are often some flammable and explosive gases in the paint room, such as toluene, xylene, gasoline, trichloroethylene and other flammable solvents, and the temperature in the paint room and some electrical products are the flammable and explosive gases. Offer favorable conditions. Therefore, we must install gas detectors in the paint room to continuously detect the concentration of these flammable and explosive gases in the air.

1. Due to the frequent occurrence of flammable gases in the paint production workshop, the solvent contains toluene, xylene, gasoline, trichloroethylene and other flammable solvents, which can easily form explosive mixture gases when they volatilize into the air, and the high voltage generated during electrostatic spraying Static electricity, and the open flame heat source used for heating during drying, all pose a great fire hazard. Combustible gas detection and exhaust devices should be installed in the workshop of the car paint room. The exhaust fan should use non-ferrous metal impellers to facilitate timely removal of combustible gases. The pressure relief device and indoor electrical equipment should meet I (Q-2) class fire protection requirements. At the same time, do a good job in anti-static work, spray guns and other equipment must be grounded, and operators should wear anti-static shoes. During operation, the spray speed, the working pressure of the spray gun, and the distance between the workpiece and the nozzle should be controlled.
2. Automobile paint room. The painted workpiece should be placed in a ventilated place for a period of time, and put it into the drying equipment to dry after the paint has no dripping. The paint-baking room should be equipped with automatic temperature control, alarm, over-temperature automatic power cut-off and other devices. The paint temperature is generally kept within 70 degrees. When silicon carbide plate-shaped infrared radiation is used for drying, the silicon carbide plate is not allowed to be damaged, and the resistance wire is strictly prohibited from being exposed. A safe distance of more than 100 mm should be kept between the silicon carbide plate and the workpiece in the oven. It is best to install an organic waste gas purification device. To reduce the concentration of combustible gas. When drying naturally, you should choose a well-ventilated environment, keep the temperature at 15-30 degrees, and the relative humidity should not exceed 80%.

Installing combustible gas detectors in the paint-baking room can effectively detect the concentration of combustible gases in the paint-baking room. When the concentration of detected gas in the air reaches or exceeds the set alarm point (20%LEL), the alarm host immediately sends out an audible and visual alarm. Concentration values are displayed to remind users to take safety measures.
